Abstract :
A design method of 2-dimensional perfect reconstruction filter banks for arbitrary sampling lattices is presented. Filter banks are constructed by a 2D nth band filter which consists of some delays and 2D interpolated all-pass networks. It is shown that the analysis and synthesis part is constructed by combining the polyphase structure of a 2D Nth-band digital filter and 2D discrete Fourier transform (DFT)
